Washington Convention Center prepares for inaugural balls

In preparation for the festivities surrounding President Obama's second inauguration, hundreds of people are scrambling to transform the Washington Convention Center into a three-story party place.

They started earlier this week, and now have just three days left to prepare for tens of thousands of party-goers...

In 2009, the president and first lady appeared at 10 inaugural balls. This year you'll see this scene at just two official balls - on 3 levels of the Convention Center.

The president will dance at all 3 levels.

The top floor is reserved for the Commander in Chief Ball for members of the military, the only place where you'll see the presidential seal.

One floor down a splash of color as the stage is set for Saturday's kid's inaugural concert. On Monday this same room will host some of the performers at the public inaugural ball, big enough to take up two floors.

Alicia Keys, Brad Paisley, Fun., members of the Glee cast, John Legend and many more will perform.

Down on the bottom floor, there are three continuous halls, about 473,000 square feet.

It's all standing room, where thousands of inaugural ball ticket buyers will try to catch a glimpse of the first couple.

If they're here on time, they'll see the president and first lady and Dr. biden and the vice president.

Outside, multiple layers of security fencing means attendees will have to show their ticket multiple times.

While back inside, their wallets may open and close a few times, with hefty prices for souvenir hunters - buttons, golf balls, and a limited edition poster of the president goes for $100.

And if you don't have a ticket, for the first time, you can watch a live stream of the galas on your smart phone.
